This Week in the Future, January 28-February 4, 2011

This week, we’re doing things a little differently. Resident artist Baarbarian has captured five of our most eye-catching stories of the week in this picture, but to win a t-shirt adorned with it, you won’t have to guess all five correctly. Instead, you’ll have to tell us which story is your favorite and why–in less than 140 characters.

The rules are as follows: We want to hear which of these five stories, linked below, is your favorite and why. Doing so is easy: Follow us on Twitter (where we go by the name @popsci, oddly enough) and fire off a tweet with your feelings on one of these stories, condensed into 140 characters. Mention us at the start of the tweet and end it with the hashtag #TWITF, and our favorite will be the proud recipient of this week’s sweet Baarbarian-inked t-shirt (which you can also buy here, if contests aren’t really your thing). Here are the options:

And don’t forget to check out our other great stories from this past week–especially our reports from Nathan Myhrvold’s Modernist Cuisine laboratory in Seattle.
